What is Hydroelectric Energy?

Hydroelectric energy is a renewable energy source like wind and solar energy. Among other renewable energy sources, the type of energy with the most well-established technology belongs to hydroelectricity. It is known that the power of water has been used since the early periods of civilization. People benefited from hydroelectric energy thanks to water mills and boats. Before the industrial revolution in the 19th century, water mills provided power for many production activities. However, due to technological inadequacies, the energy produced could not be stored and was insufficient for industrialization, which led people to turn to other fossil fuels, especially coal.

Hydraulic energy provides benefits in various fields such as modern agriculture, irrigation, tourism and sports activities. But the most important of all is the production of electricity. Today, thanks to water turbines, kinetic energy is obtained from the power of water. The first hydroelectric power plant was established in America in 1882. In 2016, the world’s largest hydroelectric power plant was established in China. It is known that this power plant has a production capacity of 22,400 MW.

How Does Hydroelectric Energy Work?

Water has high potential energy when stored behind the dam. When this water is released towards the turbines, this potential energy turns into kinetic energy. When water spins turbines, the turbines are connected to a generator and this rotational motion produces electrical energy.

How to Classify Hydroelectric Power Plants?

Hydroelectric power plants are classified according to 6 separate criteria. These criteria are as follows:

According to storage method
According to installed power
According to the typology of the dam body
According to the capacity to meet the needs of the national electricity system.
Depending on the location of the power plant building.

What are the Types of Hydroelectric Power Plants?

Depending on the type of development, hydroelectric power plants can be divided into three types:

Water Retention Facilities: A large-scale water reservoir is obtained by establishing dams. The most common use of hydroelectric power plants is through dam installation. Electrical energy is produced by the water passing through the turbines in the dam.

Pumping Facilities: Pumping facilities are established as a second water reservoir at the bottom of the established dams. Pumping facilities are very similar to water retention facilities. Water stored for future use can be pumped to the upper reservoir when needed.

Stream Facilities: Electrical energy obtained from natural water flow. Part of the stream passes through turbines. Dam installation is not possible.

Part of a hydroelectric power plant

The hydroelectric power plant consists of the following parts:

Dams: These are responsible for intercepting rivers and maintaining water bodies (for example, reservoirs) before containment, creating a difference in the water used for energy production. Dams can be made of mud or concrete (most commonly used).

Spillway: They are responsible for releasing some of the water that stops passing through the engine room and can be used for irrigation needs. They are located on the main wall of the dam and can be bottom or surface. Huge amount of water is lost in the basin at the foot of the dam to avoid damage when the water falls.

Water intake : They are responsible for collecting the intercepted water and transporting it to the machine through forced channels or pipes. The water inlet has a gate to regulate the amount of water reaching the turbine and a filter to prevent the passage of foreign objects (logs, twigs, etc.).

Power plant : The machine (generator turbine, hydraulic turbine, shaft and generator) and control and regulation elements are located here. Has an inlet and outlet to leave the machine area without water during maintenance or disassembly.

Hydraulic turbines : They are responsible for using the energy of the water passing through them to produce rotational movement through their own axis. There are three main types:

Pelton wheel,
Francis turbine, and
Kaplan turbine (or propeller).

Transformer – An electrical device is used to adjust the voltage in an alternating current circuit while keeping the power steady. This device can increase or decrease the voltage as needed.

Power transmission lines : cables that transmit the generated energy.

What are the Usage Areas of Hydroelectric Power Plants?

Electricity Production: Hydroelectric energy is mainly used to produce electrical energy. Hydroelectric power plants are favored due to their lower cost and less harmful impact on the environment compared to other energy sources. The installation of hydroelectric power plants is increasing because it does not pose serious threats to nature and human life, as in the installation of fossil fuels and nuclear power plants.

Agriculture: Thanks to hydroelectric energy, large agricultural areas can be irrigated. Flour can be produced by grinding grain with mills built with the power of water. The first civilization in history to establish hydroelectric power plants for the purpose of agricultural irrigation activities was the Egyptian civilization.

Industrial Use: It is known that bellows were driven by the establishment of hydroelectric facilities in the ancient civilization ages.

Use to Close the Energy Gap: As fossil fuels such as gasoline, coal and natural gas are becoming depleted, the trend towards other natural resources has increased to meet the energy needs. In addition to solar and wind energy, water power is also utilized in this context.

Pros of Hydroelectric Energy

There are a number of examples with the advantages of hydroelectric energy, also known as dams. Compared to fossil energies, this type of energy is a promising technology. Let’s see the advantages of this type of energy obtained from the movement of water.

It is a renewable and sustainable energy

The kinetic energy of flowing water is used to generate electricity from hydroelectric energy. Although it may cause some difficult and environmental climate problems, it is currently a strong and sustainable energy source.

It is an eco-friendly and clean energy source

The energy produced by hydroelectric power plants does not create toxic or greenhouse gasses that pollute the atmosphere. They release less greenhouse gasses than fossil-based power sources. This helps reduce climate change, acid rain and smog. It can also improve air quality because they do not emit air pollutants.

It is a useful system for sustainable development

Can develop in an economically viable, environmentally sound and socially responsible manner. Hydroelectric enterprises operated in this way represent the best concept of sustainable development. It attracts various industries and provides an overall boost to trade.

It is the country’s domestic power source

Unlike fossil fuels, hydroelectric production does not require the system to be transported over long distances. There is no mining involved in the hydroelectric production in question. The power plant installed will convert water into energy.

Supports guaranteed energy and price stability

Despite expensive upfront building costs, hydroelectric power plants are a cost-competitive energy source. River water is a domestic resource that, unlike fuel oil or natural gas, is not subject to market fluctuations.

In addition, it is the single largest source of renewable electricity. The cost-benefit ratio, efficiency, flexibility, and reliability of thermal power plants contribute to optimizing their use.

Creates jobs and employment

Hydroelectric power plants are beneficial for regions with high unemployment rates. Building these plants provides job opportunities and enhances living standards for the local community. This leads to a rise in average income, boosting consumption and tax revenues.

Contributes to the development of remote communities

Hydroelectric power plants provide electricity to remote communities. It attracts the construction of highways, industry and commerce. All these activities are aimed at stimulating the economy of these remote areas and increasing access to education and healthcare. And it serves to improve the overall quality of life of residents.

Creates entertainment and tourism opportunities

The lake formed behind the dam can be used for activities such as fishing, boating and swimming. The water of the lake can also be used for irrigation purposes. Apart from this, large dams are becoming a hotspot for tourist attractions. It could provide an economic boost to nearby towns.

Cons of Hydroelectric Energy

Hydroelectric energy has advantages as well as disadvantages. The negative effects of these power plants are generally on the environment and local ecology. Here are some definite cons of hydroelectric power.

Environmental Impact

Disruption of natural water flow can have a huge impact on the environment and river ecosystem. Hydroelectric facilities may affect the lands in the dam area, forests, swamps and grasslands in the valley. Reservoirs can include people’s homes, natural areas, and farmland.

Areas that were previously covered with water may dry out, and dry ones may become covered with water. In turn, many animal and plant species may be mixed due to these changes in natural habitats. This may cause species to decline. It can also lead to imbalance in local ecosystems.

High construction costs

Constructing these plants and dams can be incredibly expensive. Additionally, projects take a long time to complete. It will need to be operated for a long time to earn back the money spent on construction.

Limited reservoirs

Although water is an unlimited resource, the conditions required to build a dam are limited. For the efficient production of hydroelectricity, large rivers or streams that will provide sufficient water are needed. It is difficult to find a suitable location that has a large water supply throughout the year, the right amount of water, and is close enough to existing power lines.

Drought potential is high

If hydroelectric energy is to be established, water abundance and drought cycles should be taken into consideration. This usually occurs in areas with local drought.

Border conflicts may occur

Rivers often represent the border between two countries. Decisions regarding the construction of hydroelectric power plants are in question. Both countries need to agree that this construction meets the goals of both countries.

If one country wants to build a hydroelectric power plant and the other country does not, this could even lead to wars between countries in the worst case.

May cause relocation due to flood risk

The local population living in the area may become vulnerable to floods due to possible water flows from dams. As a result, people are forced to relocate to facilitate the construction of the dam needed to generate hydropower. According to the report published in 2000, the World Commission on Dams estimated that dams physically displaced 40-80 million people worldwide.

Causes deterioration of water quality

When dams are created, they limit water flow, which affects oxygen levels in the water. Lower oxygen levels behind the dam can also result in lower oxygen levels downstream. When there isn’t as much oxygen in the water, it’s harder for some fish species to survive, affecting river habitats.

Conclusion:

Everything you need to know about portable solar panels

Published

3 months ago

April 20, 2024

Sidra Yousfazai

Portable solar panels offer new freedom. They allow you to have a power supply everywhere. Space-saving and very efficient, they increase your autonomy on vacation and during all your travels.

Table of Contents

What are portable solar panels?

Portable solar panels are miniature photovoltaic panels that convert the sun’s energy into electricity. They can power a charger or a portable battery. Lightweight and designed to be used everywhere, they allow you to charge all electronic devices : smartphone, camera, tablet, GPS, laptop, camera. With a panel measuring 32 x 17 cm and only 3 mm thick, you will be able to supply electricity to all your small devices such as smartphones or sports cameras. A 6W panel can produce 1500 to 3300 mAh per day.

Portable solar panels are suitable for all outdoor leisure activities: skiing, hiking or the beach. If you travel by motorhome, by boat or if you go trekking, you will considerably increase your energy autonomy.

The panel provides electricity directly or stores it in a miniature battery . This is external for high-power panels or integrated inside a module for extra-flat flexible panels . It is then possible to use the stored energy on cloudy days or even at night.

Portable solar panels offer efficiencies of 10% to 23%. Charging times are almost identical to those of the original chargers. If the panel is used live, one hour of charging provides 10 minutes of communication with a mobile phone.

Large models can be folded to save space. An unfolded panel of 47 x 21 cm takes up only 21 x 13.5 cm when folded. Reinforced eyelets make attachment easier. The weight of solar panels varies from 150 g to 2.5 kg. Smaller models have a USB connection.

More powerful panels offer a 12V or 18V output. High-end models are particularly efficient because they have most often been designed for military use. They are therefore suitable for intensive use, even in extreme conditions.

Two main types of portable solar panels

There are two types of portable solar panels:

single-layer panels:

There are two subtypes; monocrystalline silicon models and so-called amorphous models. Monocrystalline panels are the least expensive. Amorphous silicon panels are lighter and stronger but cost 20 to 30% more. The efficiency of amorphous silicon panels is lower (around 10%) but they can be used over a wider time range.

thin-layer flexible panels:

These so-called second or third generation panels are made up of several layers. They have excellent performance and remain effective even when the light is reduced. Several materials can be used for their design:

amorphous silicon;
and CIGS ;
with CdTe;
organic polymers.

Flexible solar panels are thin and light. They can fit anywhere. The multifunction panels allow you to recharge external batteries but also a laptop.

Main advantages and disadvantages

Solar chargers are very useful for all outdoor trips. Batteries have a limited useful life, so it can be very useful to have a backup electrical source when you spend several hours or several days without access to a fixed electrical installation.

The main advantages of portable solar panels are:

their practicality : they are light, compact;
their effectiveness : they are resistant and waterproof
and their hardiness : they can withstand temperatures from -40° to +60°.

Besides their many advantages, portable solar panels do have some disadvantages:

Sometimes limited compatibility: you must ensure before purchasing that the portable panel is compatible with the devices to be recharged.

As mobile devices need a constant power supply to properly recharge their battery, it is advisable to use a buffer battery when the weather is cloudy,

Some high-power batteries require the use of a voltage regulator or solar booster to regulate the charge and protect the system.

Mobile solar panels are more expensive per 100 watt peak than regular solar panels.

For these reasons, it is recommended that you consider mobile solar panels if you want to use them in a place where there is no electricity grid. In that case, it is an excellent sustainable alternative to provide yourself with electricity. Do you want to use solar power at home? Then traditional solar panels are more efficient.

FAQs:

How does a portable solar battery work?

Solar panels generate direct electric current (DC), which is subsequently directed to the solar battery. The battery consists of reversible electrochemical accumulators, making it rechargeable. Subsequently, the energy extracted from the battery passes through the inverter.

What are the three types of solar panels?

There are three distinct types of solar panels, each with its own unique characteristics and energy production methods. These include thermal panels, photovoltaic panels, and hybrid models.
